I-Macrobrachium rosenbergii isatshalaliswa kabanziizimfanzi zamanzi ahlanzekilenenani eliphezulu lokudla okunempilo kanye nesidingo esikhulu semakethe.

Izindlela zokuzalanisa eziyinhloko zeIzimfanzi ze-Rochezimi kanje:
1. I-aquaculture eyodwa: okungukuthi, ukutshala izimfanzi ze-Roche kuphela emanzini owodwa hhayi ezinye izilwane zasemanzini. Izinzuzo zalolu hlobo lokulima ukuphatha okulula kanye nenzuzo ephezulu, kodwa ububi budingeka izinga eliphezulu lamanzi, ukuvela kalula kwezifo kanye nokuhlaselana.
2. I-aquaculture exubile: ibhekisela ekutshalweni kwezimfanzi ze-Roche nezinye izilwane zasemanzini njengezinhlanzi, iminenke, ama-clams, njll emanzini afanayo. Inzuzo yale modeli ye-aquaculture ukusebenzisa indawo enezingqimba eziningi zomzimba wamanzi, ukuthuthukisa ukukhiqizwa kwamanzi, ukukhulisa imithombo yemali engenayo, nokunciphisa ukuncintisana kanye nokuzingela phakathi kwezimfanzi ze-Roche, ngaleyo ndlela kuncishiswe ukuvela kwezifo. Kodwa okubi ukuthi ukuphatha kuyinkimbinkimbi, futhi kufanele kuqashelwe ekukhethweni nasengxenyeni yezinhlobo ezizalanayo ukuze kugwenywe ukuthonyana kanye nokubamba ukudla.

3. I-Crop rotation aquaculture: ibhekisela ekutshalweni ngokushintshana kwe-Procambarus clarkii nezinye izilwane zasemanzini emanzini afanayo ngokuya ngokulandelana kwesikhathi esithile, njengokufuywa kwezimfanzi emasimini erayisi kanye nokufuywa kwezinhlanzi emasimini elayisi. Ubuhle balo mfuziselo wokufuywa kwezilwane zasemanzini ukusebenzisa ngokugcwele izinguquko zesizini ezindaweni ezihlala emanzini, ukuzuza izinzuzo ezimbili emikhiqizweni yasemanzini nasezitshalweni, kuyilapho futhi kuthuthukiswe indawo ezungezile yemvelo yemithombo yamanzi kanye nokunciphisa ukuvela kwezifo. Kodwa okubi ukuthi kufanele kuqashelwe ukuhlelwa komjikelezo wokuzalanisa ukuze kugwenywe ukugxambukela kanye nomthelela phakathi kwemikhiqizo yasemanzini nezitshalo.

Izinzuzo kanye Nezinselelo Zobuchwepheshe Bokulima Be-Roche Shrimp:

1. Izinzuzo zobuchwepheshe bokulima izimfanzi e-Roche ikakhulukazi zihlanganisa lokhu okulandelayo:
I-Roche shrimp ingumkhiqizo wasemanzini onenani eliphezulu onomsoco ophezulu kanye nesidingo esikhulu semakethe, esingaletha izinzuzo eziphezulu zezomnotho.
2. I-Roche shrimp iyisilwane se-omnivorous esinobubanzi bokudla okubanzi, esingasebenzisa ukudla kwemvelo kanye nenani eliphansi lokuyenga emanzini ukuze kuncishiswe izindleko zokuzalanisa.
3. I-Roche shrimp iyisilwane esivumelana nezimo kakhulu esinezinhlobonhlobo zamazinga okushisa okuphila kanye nosawoti, futhi singakhuliswa emanzini ahlukene, okwandisa ukuguquguquka kwe-aquaculture.
4. I-Roche shrimp iyisilwane esikhula ngokushesha esinomjikelezo omfushane wokukhula kanye nesivuno esikhulu, esinganciphisa umjikelezo wokuzalanisa futhi sithuthukise ukusebenza kahle kokuzalanisa.
5. I-Roche shrimp iyisilwane esilungele ukulima okuxubile kanye nokulima ngokushintshanisa izitshalo, okungase kuhambisane nezinye izilwane zasemanzini nezitshalo, kuthuthukise ukukhiqizwa kwamanzi, futhi kuzuze ukuthuthukiswa okuhlukahlukene kwe-aquaculture nezolimo.
Izinselelo zobuchwepheshe bokulima izimfanzi e-Roche zifaka phakathi lokhu okulandelayo:
1. I-Roche shrimp iyisilwane esinezidingo eziphezulu zekhwalithi yamanzi, futhi ukukhula nokuthuthukiswa kwayo kuthinteka kakhulu izinga lamanzi. Kudingeka ukuqinisa ukuqapha nokuphathwa kwekhwalithi yamanzi ukuze kuvinjelwe ukungcoliswa kwamanzi kanye nokuwohloka.
2. I-Roche shrimp iyisilwane esivame ukungenwa izifo, esinokuzivikela okuphansi futhi singaba sengozini kumagciwane anjengamabhaktheriya, amagciwane, isikhunta, nama-parasites. Ngakho-ke, kuyadingeka ukuqinisa ukuvimbela nokulawula izifo ukunciphisa ukufa nokulahlekelwa kwe-Roche shrimp.
3. Izimfanzi ze-Roche yisilwane esijwayele ukudlwengulwa, sinomehluko omkhulu ngokwesilinganiso sobulili nobukhulu bomzimba, okungaholela emncintiswaneni nokuhlasela phakathi kwezimfanzi zesilisa. Ngakho-ke, kuyadingeka ukuqinisa ukulawula isilinganiso sobulili kanye nokufana kosayizi womzimba ukuze kuncishiswe izingxabano nokulimala phakathi kwezimfanzi ze-Roche.
4. I-Roche shrimp iyisilwane esithintekayo ngenxa yokuguquguquka kwemakethe, futhi intengo yayo nesidingo siyahlukahluka kuye ngezinkathi zonyaka nezifunda. Kuyadingeka ukuqinisa uphenyo lwemakethe nokuhlaziya, ukwakha isikali esiphusile nezinjongo zokuzalanisa, futhi kugwenywe ukungalingani kwezidingo zokuhlinzekwa kwezidingo kanye nokwehla kwentengo.

I-DMPT (i-Dimethyl - β - Propionate Thiophene) inezinzuzo ezilandelayo ezibalulekile ekulimeni kwezilwane zasemanzini, ikakhulukazi ekufuyweni kwezimfanzi:

1. Ukuthuthukisa ukusebenza kahle kokudla
I-DMPT inyusa kakhulu imvamisa yokudla nesivinini, ifinyeza isikhathi sokudla, futhi yehlise imfucuza yokudla ngokuvuselela ama-receptors anukayo kanye nama-gustatory. Ucwaningo luye lwabonisa ukuthi ukwengeza i-DMPT ekudleni kungakhuphula izinga lokusebenzisa cishe ngo-25% -30% futhi kunciphise ingozi yokungcoliswa kwamanzi. .
Ukukhuthaza ukukhula kanye molting.
2. I-DMPT ingasheshisa umjikelezo we-molting wezimfanzi futhi ifinyeze umjikelezo wokukhula. Ngaleso sikhathi, ukwakheka kwayo okuqukethe isulfure kungakhuthaza umzimba we-amino acid, kuthuthukise ukusetshenziswa kwama-amino acid, futhi kuthuthukise ukusebenza kahle kokukhula. .
3. Thuthukisa ikhwalithi yenyama kanye nenani lezomnotho.

4. I-DMPT ingathuthukisa ukunambitheka kwenyama yezimfanzi, inikeze izimfanzi zasemanzini ahlanzekile ukunambitheka okusha nokumnandi okufana nokwenziwa kwezimfanzi zasolwandle, kuthuthukise ukuncintisana kwemakethe. .

5. Ukuphepha kanye Nokuvikelwa Kwemvelo.

6. Izimfanzi ze-DMPT azinabo ubuthi, zinezinsalela eziphansi, futhi zihlangabezana nezidingo ze-aquaculture eluhlaza.
